Wearable biopotential measurement using the TI ADS1198 analog front-end and tex...
Pereira, Tiago; Carvalho, Helder; Catarino, André P.; Dias, M. J.; Postolache, Octavian; Girão, Pedro S.The development of mobile systems for monitoring bioelectric signals outside a hospital environment involves many challenges that do not arise when it is in a controlled environment, like a hospital. The dimensions of these systems are an important factor to consider in order to facilitate their use without interfering with the daily activities of individuals. The purpose of this work is the implementation of a...
Treat me well : affective and physiological feedback for wheelchair users
Postolache, Octavian; Girão, Pedro; Ribeiro, Mário; Carvalho, Helder; Catarino, André P.; Postolache, GabrielaThis work reports a electrocardiograph and skin conductivity hardware architecture, based on E-textile electrodes, attached to a wheelchair for affective and physiological computing. Appropriate conditioning circuits and a microcontroller platform that performs acquisition, primary processing, and communication using Bluetooth were designed and implemented. To increase the accuracy and repeatability of the ski...
Continuous health monitoring using e-textile integrated biosensors
Catarino, André P.; Carvalho, Helder; Dias, M. J.; Pereira, Tiago; Postolache, Octavian; Girão, Pedro S.In this work, continuous health monitoring for disabled or elderly people is proposed using textile integrated electrodes for ECG measurement. Other applications, such as EMG or skin impedance measurement are also envisaged. The paper specifically describes a shirt integrating electrodes for ECG measurement that has been tested in several conditions. The techniques for integration of ECG electrodes can be direc...
